Happy Birthday, Selena Gomez!

Selena Gomez's career is a teen dream come true. At just 15, her star status rose when she was cast in Disney's Wizards of Waverly Place; at 17, she launched her own fashion line, Dream Out Loud; at 19, she dated megastar Justin Bieber; and at 20, she already has three studio albums under her belt and a fourth, Stars Dance, out tomorrow. To celebrate Gomez's 21st birthday, we're raising a glass to her impeccable style.
